[0002] An insulated gate bipolar transistor (IGBT) is a semiconductor device widely used in the field of power electronics. Existing IGBT processing equipment typically places the IGBT raw materials into a vibratory feeder, and then transports each IGBT raw material to the processing station in sequence through the vibratory feeder and conveying mechanism. However, the IGBT raw materials may be damaged under the vibration of the vibratory feeder, and this method of feeding is difficult to meet the needs of large-scale processing. Utility Model Content

[0003] The purpose of this application is to provide a safe, reliable, and fast IGBT feeding device.

[0004] To achieve the above objectives, the technical solution adopted in this application is: to provide an IGBT feeding device, comprising:

[0005] The frame is equipped with guide rails for supporting IGBT raw materials;

[0006] A material feeding mechanism is mounted on the frame, and the material feeding mechanism is used to drive the material box to rotate and move between the feeding position and the material feeding position;

[0007] The guiding mechanism includes an inclined transition plate having a groove suitable for sliding IGBT raw materials, the outlet of which is connected to one end of the guide rail.

[0008] A feeding mechanism is provided on the frame and located next to the unloading mechanism. The feeding mechanism includes a storage bin for stacking and storing multiple material boxes and a first power source for conveying the material boxes in the storage bin to the loading position.

[0009] When the material feeding mechanism rotates the material box to the feeding position, the IGBT raw material can slide out of the material box into the chute in sequence by its own gravity, and then slide down onto the guide rail through the chute.

[0010] In one embodiment, the feeding mechanism further includes a drive plate connected to the first power source. The top surface of the drive plate is provided with a slot with a width suitable for the material box. The first power source can drive the drive plate to move between a clamping position and a discharging position. When the drive plate is in the clamping position, a material box at the bottom of the storage bin falls into the slot. When the drive plate is in the discharging position, the material box moves to the feeding position.

[0011] In one embodiment, the frame has a horizontally arranged support plate at one end away from the guide rail. The unloading mechanism includes a rotating seat, a lifting plate, and a second power source. The rotating seat is rotatably connected to the frame, and the lifting plate is movably disposed on the rotating seat. The output end of the second power source is hinged to one end of the rotating seat. The support plate and the rotating seat form a support platform for placing the material box. The lifting plate is configured such that after the feeding mechanism pushes the material box to the support platform, it descends to press one end of the material box against the rotating seat, and rises to a predetermined position when the empty material box rotates to a horizontal position. The second power source is used to drive the rotating seat to rotate, thereby causing the material box to rotate and move between the loading position and the unloading position.

[0012] In one embodiment, a hollow guide block is provided on the top surface of the rotating seat near the end of the transition plate. The guide block is provided with a guide groove suitable for the IGBT raw material to slide through. The inlet of the guide groove is connected to one end of the material box located on the support platform. When the rotating seat drives the material box to rotate to the pouring position, the outlet of the guide groove is connected to the inlet of the chute.

[0013] In one embodiment, a buffer mechanism is provided at the end of the material pouring mechanism away from the discharge port. The buffer mechanism includes a fixed frame connected and fixed to the material pouring mechanism, a drive cylinder on the fixed frame, and a buffer block at the output end of the drive cylinder. The drive cylinder drives the buffer block to move between a first position and a second position. When the empty material box is rotated to a horizontal state by the material pouring mechanism, the buffer block is located at the first position and is suspended above the empty material box. When the material pouring mechanism drives the material box to rotate, the buffer block is located at the second position and abuts against the top surface of the material box.

[0014] In one embodiment, the discharge end of the feeding mechanism is provided with a discharge sensor that is communicatively connected to the second power source. When the discharge sensor detects that there is IGBT raw material at the discharge port of the material box, it controls the second power source to maintain the current state. When the discharge sensor detects that there is no IGBT raw material at the discharge port of the material box, it controls the second power source to drive the rotating seat to rotate to a horizontal state.

[0015] In one embodiment, a limiting block is provided at the end of the guide rail away from the transition plate to restrict the IGBT material from continuing to slide forward along the guide rail.

[0016] In one embodiment, the guide rail has a waiting area near the transition plate and an operating area away from the transition plate. The IGBT feeding device further includes a pressing mechanism, which includes a third power source and a pressing plate. The third power source drives the pressing plate to press the IGBT raw material located in the waiting area to restrict the IGBT raw material from sliding from the waiting area to the operating area.

[0017] In one embodiment, the IGBT feeding device further includes a positioning mechanism. A fixed plate is provided on the side of the guide rail away from the positioning mechanism. The positioning mechanism includes a positioning plate and a fourth power source for driving the positioning plate to move. The height of the top of the positioning plate is higher than the height of the bottom surface of the IGBT material and lower than the height of the pin of the IGBT material. The fourth power source is configured to drive the positioning plate to abut against one end of each IGBT material located on the guide rail, so that the other end of each IGBT material abuts against the fixed plate.

[0018] In one embodiment, the transition plate has an arc-shaped section at one end near the guide rail, so that the IGBT raw material can slide stably down the guide rail through the arc-shaped section.

[0019] The beneficial effects of the IGBT feeding device provided in this application are as follows: Compared with the prior art, in the IGBT feeding device of this application, when the first power source of the feeding mechanism transports the material box to the feeding station, the unloading mechanism rotates the material box to the same angle as the transition plate, so that each IGBT material in the material box can slide out of the material box in sequence under its own gravity and slide down from the transition plate onto the guide rail. The overall structure is simple, and there is no need to use a vibration mechanism to achieve feeding, which will not damage the IGBT material. It is safe and reliable, and the feeding speed is fast. Multiple IGBT materials can be transported to the guide rail at one time, which can meet the needs of large-scale rapid processing. Attached Figure Description

[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0033] Please refer to the following: Figures 1 to 4 The IGBT feeding device provided in this application embodiment will now be described. The IGBT feeding device includes a frame 10, and a feeding mechanism 40, a discharging mechanism 20, and a guiding mechanism 30 disposed on the frame 10. A guide rail 13 for supporting IGBT raw materials 1 is provided on the frame 10, and the arrangement direction of the guide rail 13 is parallel to the length direction of the frame 10. The material box 15 is a hollow, elongated shell, with multiple IGBT raw materials 1 arranged in a straight line inside. The material box 15 has openings at both ends along its length. The discharging mechanism 20 is used to rotate and move the material box 15 between the feeding position and the discharging position. The material box 15 is horizontal when in the feeding position and tilted when in the discharging position.

[0034] The guiding mechanism 30 includes an inclined transition plate 31 with a chute 310 suitable for sliding the IGBT raw material 1. The inlet of the chute 310 is connected to the outlet of the pouring mechanism 20, and the outlet of the chute 310 is connected to one end of the guide rail 13. The guiding mechanism 30 also includes a cover plate on the transition plate 31, so that the guiding mechanism 30 is a plate structure with openings at both ends, making it difficult for the IGBT raw material 1 to escape from the chute 310 after falling into it.

[0035] Specifically, the frame 10 includes a first frame 11 and a second frame 12 connected to each other. The top surface of the second frame 12 is lower than the top surface of the first frame 11. A guide rail 13 is fixed to the second frame 12. A transition plate 31 is obliquely fixed to one end of the second frame 12 near the first frame 11 via a support frame. The oblique angle of the transition plate 31 is 30 to 45 degrees. Both the first frame 11 and the second frame 12 are equipped with support frames and casters at their bottoms, which facilitates the movement of the entire frame 10.

[0036] The feeding mechanism 40 is located beside the unloading mechanism 20. The feeding mechanism 40 includes a storage bin 41 and a first power source 42. The storage bin 41 is used to stack and store multiple material boxes 15, and the first power source 42 is used to transport the material boxes 15 in the storage bin 41 to the loading position.

[0037] Specifically, the first power source 42 transports a material box 15 from the storage bin 41 to the loading station. When the unloading mechanism 20 rotates the material box 15 located at the loading station to a predetermined angle, the material box 15 is in the unloading position. At this time, one end of the material box 15 is aligned with the entrance of the slide groove 310 of the transition plate 31. The IGBT raw material 1 in the material box 15 slides down from the material box 15 into the slide groove 310 in sequence, and then slides down from the slide groove 310 to the guide rail 13, so that multiple IGBT raw materials 1 are arranged in sequence on the guide rail 13. This completes the entire loading operation of IGBTs, in preparation for the subsequent lead shearing and bending operation.

[0038] Compared with the prior art, the IGBT feeding device provided in this application has the following advantages: when the first power source 42 of the feeding mechanism 40 transports the material box 15 to the feeding station, the unloading mechanism 20 rotates the material box 15 to the same angle as the transition plate 31, so that each IGBT material 1 in the material box 15 can slide out of the material box 15 in sequence under its own gravity and slide down from the transition plate 31 onto the guide rail 13. The overall structure is simple, and there is no need to use a vibration mechanism to achieve feeding. It will not damage the IGBT material 1, is safe and reliable, and has a fast feeding speed. It can transport multiple IGBT material 1s to the guide rail 13 at one time, which can meet the needs of large-scale rapid processing.

[0039] See Figure 2 The transition plate 31 has an arc-shaped section 311 at one end near the guide rail 13, which allows the IGBT material 1 to slide stably onto the guide rail 13. If the arc-shaped section 311 is not provided, the connection between the transition plate 31 and the guide rail 13 will not be smooth, and one end of the IGBT material 1 may press against the end of the guide rail 13, thus preventing subsequent IGBT material 1 from flowing smoothly onto the guide rail 13.

[0040] See Figure 1 , Figure 4 and Figure 5The feeding mechanism 40 also includes a drive plate 43 connected to the first power source 42. The storage bin 41 includes two clamping plates 410 spaced apart on the frame 10, with a plurality of stacking slots 411 formed between the two clamping plates 410, suitable for stacking material boxes 15. The bottom of each stacking slot 411 may be provided with an elastic element. The top surface of the drive plate 43 is provided with a slot 431 of suitable width for the material box 15. The first power source 42 can drive the drive plate 43 to move between a clamping position and a discharging position. When the drive plate 43 is in the clamping position, one material box 15 at the bottom of the stacking slot 411 falls into the slot 431 of the drive plate 43. When the drive plate 43 is in the discharging position, the material box 15 moves to the loading position. Specifically, the drive plate 43 includes two spaced-apart support plates 430 and a connecting plate 432 connected to the bottom surface of the two support plates 430. The connecting plate 432 and the two support plates 430 form an I-shaped structure. The two support plates 430 are slidably engaged with slide rails on the frame 10 via sliders. The slide rails are arranged parallel to the width direction of the frame 10. The connecting plate 432 is connected to the output end of the first power source 42, so that the first power source 42 drives the two support plates 430 to move back and forth through the connecting plate 432. The top surfaces of the two support plates 430 are respectively provided with slots 431, the depth of which is less than the thickness of the material box 15. The first power source 42 may be, but is not limited to, a cylinder. After the unloading is completed, the empty material box 15 is rotated to the loading position by the unloading mechanism 20, while the feeding mechanism 40 continues to push the material box 15. One end of the two pallets 430 pushes the empty material box 15 out of the loading position, and the empty material box 15 falls into the collection box 14 on one side of the frame 10.

[0041] See Figures 3 to 5The frame 10 has a horizontally arranged support plate 17 at one end away from the guide rail 13. The material feeding mechanism 20 includes a rotating seat 21, a lifting plate 22, and a second power source 23. The rotating seat 21 is rotatably connected to the frame 10. The frame 10 has a fixed block 19. The bottom surface of the rotating seat 21 has two spaced connecting blocks 25. The two connecting blocks 25 are rotatably mounted with a rotating shaft 26 via bearings. The rotating shaft 26 rotatably passes through the fixed block 19. The lifting plate 22 is movably mounted on the rotating seat 21. The output end of the second power source 23 is hinged to one end of the rotating seat 21. The support plate 17 and the rotating seat 21 form a support platform for placing the material box 15. The material box 15 is fed onto this support platform. The frame 10 has multiple support members 27. When the rotating seat 21 is in a horizontal position, its bottom surface abuts against the top surface of the support member 27. The lifting plate 22 is configured as a feeding mechanism 40 to push the material box 15 to the support platform and then descend to press one end of the material box 15 against the rotating seat 21. When the empty material box 15 rotates to the horizontal position, it rises to a predetermined position. The second power source 23 is used to drive the rotating seat 21 to rotate, thereby driving the material box 15 to rotate and move between the feeding position and the unloading position. That is, the second power source 23 can drive the material box 15 to rotate from the horizontal position to the inclined position, and drive the empty material box 15 to rotate from the inclined position to the horizontal position. The second power source 23 specifically includes a drive cylinder 52 and a connecting rod 230. The drive cylinder 52 is set in the frame 10. One end of the connecting rod 230 is connected to the output shaft of the drive cylinder 52, and the other end is hinged to the rotating seat 21. A connecting frame 28 with a U-shaped longitudinal section is installed on the bottom surface of the rotating seat 21. A fixed shaft is provided on the connecting frame 28, and the other end of the connecting rod 230 is rotatably connected to the fixed shaft, thus realizing the hinge between the connecting rod 230 and the rotating seat 21.

[0042] See Figure 2 , Figure 3 , Figure 5 A hollow guide block 24 is provided on the top surface of the rotating base 21 near the transition plate 31. The guide block 24 has a guide groove 240 suitable for the IGBT raw material 1 to slide through. The inlet of the guide groove 240 is connected to one end of the material box 15 located on the support platform. When the rotating base 21 drives the material box 15 to rotate to the unloading position, the outlet of the guide groove 240 is connected to the inlet of the slide 310. That is to say, when the material box 15 is driven to rotate to a predetermined angle by the unloading mechanism 20, the IGBT raw material 1 in the material box 15 first passes through the guide block 24 on the rotating base 21, then slides into the slide 310 of the transition plate 31, and finally slides onto the guide rail 13.

[0043] See Figure 1 , Figure 3The discharge end of the material pouring mechanism 20 is equipped with a discharge sensor 29 that is communicatively connected to the second power source 23. When the discharge sensor 29 detects that there is IGBT raw material 1 at the discharge port of the material box 15 on the material pouring mechanism 20, it controls the second power source 23 to maintain the current state. When the discharge sensor 29 detects that there is no IGBT raw material 1 at the discharge port of the material box 15 on the material pouring mechanism 20, it controls the second power source 23 to drive the rotating seat 21 to rotate to a horizontal state. In other words, when the discharge sensor 29 detects material, the material box 15 remains in its original tilted position. If no material is detected, the material box 15 on the discharging mechanism 20 is empty. The discharging mechanism 20 then moves the material box 15 back to the horizontal position, pushing the empty material box 15 out of the discharging station of the discharging mechanism 20. The empty material box 15 falls into the adjacent collection box 14, and the new material box 15 of the feeding mechanism is transported to the discharging station to continue the feeding operation. This cycle continues until all the material boxes 15 in the feeding mechanism are used up, and then multiple new material boxes 15 are stacked in the storage area of ​​the feeding mechanism.

[0044] See Figure 1 , Figure 4 , Figure 5 The buffer mechanism 50 includes a fixed frame 51, a drive cylinder 52, and a buffer block 53. The fixed frame 51 is connected and fixed to the unloading mechanism 20, the drive cylinder 52 is mounted on the fixed frame 51, and the buffer block 53 is located at the output end of the drive cylinder 52. The buffer block 53 can be a cylindrical silicone block or an elastic injection molded part. The buffer block 53 forms a buffer section. The drive cylinder 52 can drive the buffer block 53 to move between the first position and the second position. When the empty material box 15 is rotated to a horizontal state by the pouring mechanism 20, the buffer block 53 is located in the first position and is suspended above the empty material box 15. When the pouring mechanism 20 drives the material box 15 to rotate, the buffer block 53 is located in the second position and abuts against the top surface of the material box 15. That is, the buffer block 53 can buffer the material box 15 during the process of being driven to rotate into an inclined state. The end of the material box 15 away from the guide rail 13 contacts the buffer block 53 during the swing. The setting of the buffer block 53 can reduce the swing amplitude of the material box 15, so that the material box 15 can reach a stable state more quickly. In other words, when the material box 15 moves from the feeding mechanism 40 to the support platform, there is a gap between the buffer block 53 and the material box 15. Before the material box 15 is tilted by the unloading mechanism 20, the buffer block 53 descends to abut against the material box 15. After the unloading is completed, the empty material box 15 is rotated to a horizontal position by the unloading mechanism 20. At this time, the buffer block 53 rises and the empty material box 15 is pushed out of the support platform by the drive plate 43.

[0045] See Figure 2 and Figure 6A limiting block 18 is provided at the end of the guide rail 13 away from the transition plate 31 to restrict the IGBT material 1 from continuing to slide forward along the guide rail 13. It can be understood that the guide rail 13 and the limiting block 18 can be integrally set, that is, a boss is provided at one end of the guide rail 13, and the boss forms the limiting block 18.

[0046] See Figure 1 , Figure 2 and Figure 6 The guide rail 13 has a waiting area 130 near the transition plate 31 and an operating area 131 away from the transition plate 31. The length of the operating area 131 is greater than the length of the waiting area 130. The IGBT feeding device also includes a pressing mechanism 60, which includes a third power source 61 and a pressing plate 62. The third power source 61 drives the pressing plate 62 to press the IGBT raw material 1 located in the waiting area 130 to restrict the IGBT raw material 1 from sliding from the waiting area 130 to the operating area 131. In this embodiment, the operating area 131 can hold 10 IGBT raw materials 1, and the waiting area 130 can hold 5 IGBT raw materials 1. That is, when there are 10 IGBT raw materials 1 in the operating area 131 of the guide rail 13, the third power source 61 drives the pressure plate 62 to press down the 5 IGBT raw materials 1 in the waiting area 130. When the 10 IGBT raw materials 1 in the operating area 131 are moved to the next processing position, the third power source 61 drives the pressure plate 62 to leave the waiting area 130. At this time, the IGBT raw materials 1 in the transition plate 31 push against the 5 IGBT raw materials 1 in the waiting area 130 due to their own gravity, until there are 10 IGBT raw materials 1 in the operating area 131 again, and so on.

[0047] See Figure 2 and Figure 6The IGBT feeding device also includes a positioning mechanism 70. A fixing plate 16 is provided on the side of the guide rail 13 away from the positioning mechanism 70. The fixing plate 16 is perpendicular to the top surface of the guide rail 13, and the arrangement direction of the fixing plate 16 is parallel to the length direction of the guide rail 13. The positioning mechanism 70 includes a positioning plate 71 and a fourth power source 72 for driving the positioning plate 71 to move. The fourth power source 72 is configured to drive the positioning plate 71 to abut against one end of each IGBT material 1 located on the guide rail 13, so that the other end of each IGBT material 1 abuts against the fixing plate 16. In other words, when multiple IGBT raw materials 1 slide down from the transition plate 31 and move to the guide rail 13, they may not be neatly arranged on the guide rail 13. Some of them may be skewed. If these IGBT raw materials 1 are directly transported to the next processing position, the positions of their pin cutting and bending will be inconsistent, resulting in low processing yield. The fourth power source 72 can drive the positioning plate 71 to hold each IGBT raw material 1 on the guide rail 13 against the fixing plate 16 on one side of the guide rail 13. In this way, the positioning and alignment of each IGBT raw material 1 on the guide rail 13 is achieved. When these aligned rows of IGBT raw materials 1 are moved to the next processing position, all the pins of each IGBT raw material 1 can be neatly arranged, thereby improving the product yield.

[0048] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
